Description

I get this message when I try and access the fog web page.
Database Schema Installer / Updater

Your database connection appears to be invalid. FOG is unable to communicate with the database. There are many reasons why this could be the case. Please check your credentials in /var/www/fog/lib/fog/config.class.php. Also confirm that the database is indeed running. If credentials are correct, and if the Database service is running, check to ensure your filesystem has enough space.

@Wayne-Workman Automatic Updates are already disabled on my servers. I do not update the OS once fog has been installed. It tends to break things.

Check again. All these different versions of FOG all stopped working for 4 different people… Today. The only thing in common is Ubuntu 16.04. It’s almost surely an OS update that broke it. It really couldn’t have been anything else.
